Application filed March 6, 1920. Serial No. 368,740.

To all whom it may concern:

Be it known that I, WILLIAM RIGHTER CoMrNes, a citizen of the UnitedStates, residing at Surrey, England, have invented certam new and usefulImprovements in Valves, Faucets, and the like, of which the following isa specification.

My invention relates to valves for controlling the flow through pipes ofwater, steam, gas, air, or other liqulds or fluids, and embodies a valveor faucet carrying a self-contained supply of washers and spare parts,together with tools for polishing or resur facing the valve seat orseating, and which is provided with means for readily changing orremoving a washer, and also with means for rotating the valve member forrepolishing the seating surface, and comprises the arrangements andcombinations as set forth in the claims.

In order that my invention more readily may be understood reference ismade to the accompanying drawings, in which similar letters of referencedenote corresponding parts in the several views.

. F igure 1 is a vertical longitudinal sectional'view of an ordinarywater faucet, em-

bod 'ng my improved construction.

olishing member ig. 2 is a'top plan view of Fig. 1, the operating handlebeing removed.

Fig. 3 is an enlarged detail sectional view of a reversible cutting andpolishing head.

Fig. 4 is a view similar to Fig. 1 showing a modified construction.

Fig. 5 is a detail sectional view, illustrating'still anothermodification.

Fig. 6 is a detail view of the split ring shown in Fig. 1.

Fig. 7 is a view similar to Fig. 1, showing the improvements applied toa different type of valve.

Fig. 8 is a view similar to Fig. 1 of the Fig. 7 type of valve, showinga modified form of secondary valve.

In the said drawings, referring more particularly to Figs. 1 and 2, thereference letter J denotes the valve stem of an ordina tKpe of waterfaucet having detachably fixed t ereto at its lower end, by means of ascrew F, a cutting or abrading head H, said head being grooved annularlon its outer face to receive a spring ring adapted to engage anddetachably retam a magazine member B thereon. Said magazine member Bcontains a number of spare washers E, a suitable a cushion Washer A ofrubber or other elastic material, and the washer C- disposed in positionto engage the valve seat R removably positioned in the partltlon Y ofthe valve. The valve. stem J passes through a st-ufling gland or nut Pwhlch 1s 1n screw-threaded engagement at theupper end of the valvecasing, as shown, and interposed between said nut and the lower enlargedend of said valve stem is a coiled spring 0 acting normally to forcesaid valve stem ownwardly. The upper end of the valve casing isexteriorly screw-threaded to receive the interior screw threads of ahand wheel W, said hand wheel being centrally apertured to permit thepassage there through of the smaller portion of the valve stem and sa1daperture being extended on opposite s1des into slots L adapted toreceive a clutch pin M fixed in said valve stem. Also fixed to the upperend of said valve stem is a knob or handle Z, for a purpose hereinafterto be described.

The valve seat R has a double face, which adapts it to be engaged by awasher A. and a secondary closing valve carried by valve stem J, saidsecondary valve being capable of operation to close the flow of waterthrough thefaucet when the rimary valve 1s open, of such operation isdiasired. Inasmuch as the mechanism for controlling this secondary valveforms no part of the present invention, the details of the same havebeen omitted.

. In operation, when it is desired to close the main valve, the handwheel W is screwed down, and the tension of the spring 0 at the sametime forces down the valve stem J so as to retain the clutch pin M inthe slot I until the washer C at the lower end of the magazine B engagesthe valve seat R. Further downward movement of the hand wheel W willresult in carrying the same below the clutch pin M so that the latterwill disengage from the slot in said hand wheel and the valve stem Jwill be free to be rotated independently of the hand wheel W. The resultof this operation is that as the washer C first contacts with the seat Rits downward motion will be arrest- .ed, but a limited rotary motionwill be imparted thereto, thereby polishing the seat R, which operationwill continue until the clutch pin M disengages from the hand wheel W.The spring 0 should be'ofa. strength just sufiicient to give a goodpolishing result without any tendency to cut or tear the washer. Forone-half inch water faucet I find that five to ten pounds is a suitablepressure for this purpose. By varyin the dimensions of the clutch parts,the va ve stem J may be given any desired amount of rotation before itis released, though in practice I find that one-half to a one full turngives a good result and kee V s the valve bright and clean.

v hen it is desired to recut or especiallg polish the valve seat R, thevalve stem is taken out of the valve casing by unscrewing the hand wheelW and gland nut. P. The magazine member and its contained parts areremoved, thus exposing the cutting member H in proper working position.The valve stem J then is reseated and screwed down by the hand wheel Wuntil the head H is in firm cutting contact with the valve seat R,whereupon a few turns on the fixed handle Z will recut and aline thevalve seat R with the valve stem J, as readily will be understood. If itis desired simply to repolish the valve seat R more effectually than canbe accomplished by means of the Washer C, the cutting disk may beremoved from the valve stem J, and the polishing disk N attachedthereto, and operated as hereinbefore described in res set to recuttingthe valve seat.

11 Fig. 3 I have shown a slightly modified construction, whereby thecutting disk H and polishing disk N are combined in one part in. areversible member, instead of being two separate members, as shown inFig. 1. I

Fig. 4: shows a modified construction of the attaching means for themagazine B, the same being connected with the enlarged head K at thelower end of the valve stem J by means of spring clips I instead of bymeans of the split ring G. In this construction also there is shown aslightlyv different form of secondary valve X, the same being.

provided with a stem S adapted to be en gaged by the washer G as thelatter moves into contact with valve seat R, thereby automaticallyopening said secondary valve. In this construction, the open position ofthe faucet is obtained when the valve stem J has been moved downsufiiciently to force open the secondary valve X, and yet not close theprimary valve.

Fig. 5 illustrates still another modified construction, wherein themagazine B is dispensed with and the several members are attached by thescrew F to the swivel head K. which is secured to the valve stem by ashank D and a spring ring G locking in a groove in the interior of saidvalve stem. In this connection I employ a sleeve B, retained in positionby frictional engagement with the edges of the washers E, andinturned'at its'lower edge to retain the washer C,

Fig. 7 shows the invention applied to a conventional steam valve. Wheresuch valves are subjected to very high temperature, such as would affectrubber or other cushion members, I omit the cushion member A and obtainthe elastic yielding action by forming the members E slightly dishedandthen assembling them in the magazine so as to obtain an elasticresult.

The cutting members H, I preferably make from rustless steel, and theabrasive members C and E should be made from material that is unafiectedby any chemical action from the flow of liquid, fluid or gas passingthrough the valves.

I do not limit mysel'f'herein to the precise forms and constructionsdescribed, as the same may be modified or altered in various wayswithout departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. A valve or faucet, comprising a valve stem, a magazine memberdetachably attached thereto and adapted to contain both a washer forcooperating with the valve seat and spare washers, and a split ringforming the connecting element between. said valve stem and member andengaging grooves therein.

a 2. A valve or faucet, comprising a valve stem, a resurfacing tooldetachably fixed to the lower end of said stem, and a magazine memberdetachably attached to said tool and adapted to contain both a washerfor cooperating with thevalve seat and spare washers.

3. A valve or faucet, comprising a valve stem, a resurfacing tooldetachably fixed to the lower end of said stem, a magazine memberdetachably attached to said tool and adapted to contain both a washerfor coo crating with the valve seat and spare wasliers, and a springsplit ring engaging grooves in said magazine member and resurfacing tooland forming the detachable connection between the two.

4. A valve or faucet, comprising a valve seat, a valve stem. means forimparting a rotating advance to said stem toward said seat until it hasmade polishing contact therewith and then changing said motion to astraight thrust without rotation.

5. A valve or faucet, comprising a valve seat, a valve stem, a rotatablehandle in screw-threaded engagement with the valve casing adapted toengage, rotate and advance with said stem toward said valve seat, and toautomatically disengage itself from the stem after-contact of the stemwith said seat has been madea and means for rotating ependently when sorelongitudinal and rotary movements of said handle will be imparted tosaid stem, the 10 contact of said stem and seat automaticallydisengaging said pin and slot engagement, and means for rotating saidstem independently against said seat.

In testimony whereof I afiix my si ature. 15
